A method of preserving colored images.

摘要

A method of preserving colored images formed by exposing imagewise a heat developable color photosensitive element which has a construction which includes, on a support, at least a photosensitive silver halide, a binder and a dye providing substance which forms or releases a diffusible dye in proportion, or in inverse proportion, to a reaction in which the silver halide is reduced to silver; thereafter or simultaneously heating said element to form a diffusible dye; and transferring the diffusible dye image to a dye fixing element, wherein the photosensitive element or the dye fixing element further comprises at least one of a compound of which the quenching rate constant for the excited triplet of arylazonaphthol yes is at least 1x10<5> M<-><1>.sec<-><1> and a compound of which the quenching rate constant for singlet state oxygen is at least 1x10<7> M<-><1>.sec<-><1>.
